Just bought a new SSD, now what?

[securitybreach]

Well mine is much faster than the specs show so I am happy

/dev/sda:

Timing cached reads: 21358 MB in 2.00 seconds = 10688.82 MB/sec

Timing buffered disk reads: 1522 MB in 3.00 seconds = 507.15 MB/sec

 

 

 

As a comparison.

Windows7 on a ssd 240 GB

Storage on a F3 500 GB

hdparm -Tt /dev/sde

 

/dev/sde:

Those times above are form 2014.

 

On my newly installed NVME ADATA SX8200PNP 1 TB I get this result,

 

 Put brain in gear befor pressing enter18:56:02-->Sun Dec 13-->~
-->sudo hdparm -Tt /dev/nvme0n1 

/dev/nvme0n1:
 Timing cached reads:   35968 MB in  1.99 seconds = 18111.70 MB/sec
 HDIO_DRIVE_CMD(identify) failed: Inappropriate ioctl for device
 Timing buffered disk reads: 7802 MB in  3.00 seconds = 2600.21 MB/sec

I do not know how that relates to advertised speeds for the drive which are

	Internal Data Rate 3350 MBps (read) / 2800 MBps (write) 4KB Random Read 390000 IOPS 4KB Random Write 380000 IOPS
	Swapping the os from the old nvme to this one has been one heck of a convoluted journey. I got there in the end though.

Found out that gnome-disk-utility has a component called gnome-disks which shows read and writes. You have to unmount the disk to get write data though.

 

 

 

 

 

 

I stopped the test on the Samsung F3 hd and the SanDisk usb as they were taking too long, they were there just for fun anyway. Interesting to see the difference in the 860 EVO and the Crucial ssd.

 

On arch there is a package,

 

http:// https://www.archlinux.org/packages/extra/x86_64/gnome-disk-utility/

 

once installed you can run gnome-disks from the terminal.

 

As we all have different ssd's it would be interesting to see the results for other drives.
